SPECIFICATION forming part of Letters Patent No. 474,955, dated May 17,1892.

` Application filed January 25, 1892. Serial No. 419,204. (Nor model.)

To all' whom t may concern:

Be it known that l, HENRY FLYNN, a citizen of the United States,residing at Leavenworth, in the county of Leavenworth and State ofKansas, have invented certain new and useful Improvements in Locks; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in theart to which itappertains to make and use the same, reference being had totheaccompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My invention relates to improvements in lock-casings, and has for itsobject certain improvements in the construction of such devices as willfacilitate their attachment to doors by persons who are not skilledworkmen.

Myinvention consists in providingacasing of a lock having key andknob-spindle holes with perforations or gage-holes so located that theywill form guides for boring the holes in the door for the passage of thekey and knobspindle, the relative arrangement of the gageholes and thespindle and key holes being such that when the lock is moved to itsproper position the latter holes will register with' those bored in thedoor. It is preferred to provide the casing with means for securing itto the door temporarily, so that it can be rotated upon said fastening,the perforations or gage-holes being the same distance radially from thecenter of rotation, respectively, as the key and knob-spindle holes, andwhich will have the same position with relation to each other and to theupper edge of the casing as the key and knob-spindle holes have to eachand to the latch edge of the casing, whereby, if the casing be securedby its central fastening to the door with its top edge flush with theedge of thesame, the gage-holes will form guides for boring, aspreviously stated, and when the lock is turned to its proper position,with its latch edge iiush with the edge of the door, the key andknob-spindle holes in the casing will register with the holes bored inthe door, as first stated.

The invention also consists in providing a covering for closing thegage-holes after they have served their purpose.

The invention further consists in the novel combination and arrangementof parts such as will be hereinafter more fully described, pointed outin the appended claims, and illustrated in the accompanying drawings.

In the accompanying drawings, in which similar letters of referencedesignate corresponding parts, Figurel is an elevation showing thecasing secured at a central point to the door, turned with its loweredge flush with the edge of the door, in position so that the gage-holeswill indicate the proper places to bore the holes in the door for the-key and spindle holes. Fig. 2 is a section through the casing and dooron the line :c of Fig. l, showing one of the holes bored. Fig. 3 is anelevation showing the casing in its proper position, permanently securedto the door. Fig. 4 is a section through the casing and door on the liney y of Fig. 3, showing the knob-spindle and the key in dotted lines.Fig.

5 is a detail sectional view through a portion of the casing and thedoor on the line c z of Fig. 3, showing a cap covering a gage-hole inthe casing.

Referring to the drawings by letter, A designates the door; B, thelock-casing of any construction suitable in the premises. The casing maybe of any shape, so that two of its edges or other guides are at equaldistances from the central fastening. The preferable form,'however, isrectangular, and is so illustrated in the present instance, the lowerand latch edges forming the guide-edges.

C ldesignates a screw which passes through the casing at a point on aline bisecting the angle formed by the latch and the upper edgessecuring the casing, so that it may be rotated to bring either ofthesaid edges iiush with the edge of the door.

D and E designate, respectively, the spindle and key holes formed atsuitable points inthe casing.

GV and H designate the gage-holes, which when the casing is in theproper position are guides to the boring of the holes in the door' forthe spindle and key. The relative position of the spindle and the keyholes and of the gage-holes is such that when the casing is turned withits lower edge iiush with the edge of the door the gage hole .G willform a guide for the boring of the hole for the knobspindle, and thegage-hole H will form a guide for the boring of the keyholein theirproper ing the sides of the casing before assembling,

so that when assembled the opening in each plate will register withthose in the other. To close the gage-holes to the interior of thecasing, cylindrical tubes L L are seated in them and swaged in place.

The operation of the device is as follows:

The casing is placed in the position it is desired to have -it occupyupon the door and fastened by the central fastening@ The casing is thenturned until its top edge is flush with the edge of the door, bringingthe gageholes in place to guide the borings of the holes M M in thedoor. After the boring the casing is turned to its normal position,bringing 1 the spindlev and key holes to register with the holes M andM', respectively, and permanentlysecured in place by means of thescrewholes P I). To complete the lock, the spindle and Vknobs areattached and the keyholeguard O secured in place. To give the casing a'finished appearance, covers or caps lS S are pro-vided, which, by meansof the screws T T, can be secured over the gage-holes. The

covers and their screws willalso serve to more p iirmly secure thecasing in place.

Departures in several of the details of construction can be made withoutdeparting from the spi-rit of the invention, so long as the relativepositions of the guide-lines or guide-sides to a common locus, and therelation of the spindle and key holes .to one of these lines and therelation ot' the gage-holes to vthe other line remain.

As stated, it is preferred to first pivot the lock-case to the doors, sothat itmay be turned into the two positions,.one for boring the holesand the other for 'receiving the knob-spindle and key; but it is notessential to pivot the case, as the parts can be brought into the properposition by adjusting the case by moving it sidewise or otherwise, as isobvious.

By providing the lock-case with the gageholes the lock can be applied byany other than skilled mechanics and in the minimum of time withabsolute certainty and accuracy as to the points of boring the holes andthe proper attachment of the lock-case.-

I-Iaving thus described my invention, what I claim, andv desire tosecure by Letters Patent,

I. As a new article of manufacture, a lockcasing having key and spindleholes and provided with a gage-hole or gage-holes for determining 'andvgaging the points of boring the spindle and key holes in the door',substantially as and for the purposes described.

2. The combination of the door, a casing, and means for securing thecasing so that it can be turned to bring two of its edges Hush with theedge of the door, the said casing being provided with gage-holes forboringspindle and `key holes in the door, said gage-holes being the samedistance from the pivotal point that the spindle and key holes,respectively, are from said point, substantially as described. 3. Thecombination of the door, the casing provided with gage-holes, and thecovers for said gage-holes, substantially as described.

Intestimony whereof I aix my signature in presence of two witnesses.

HENRY FLYNN.
